Discovery\Background
Around 1870, scientists believed there was a substance in cod-liver oil that treated the bone disease rickets. A scientist by the name of Sir Edward Mellanby significantly contributed to the rule of the level of Vitamin D in your body. Around 1920, a Universtiy of California study conducted an experiemnt consisting with Sir Mellanby and dogs. He worked with the young puppies in which he raised indoors. They were kept away from sun exposer and uv rays. Advised a diet that consisted of low-fat milk and bread that allowed him to establish rickets. Other scientist that helped contribute to the use of Viatmin D were Adolf Windaus and E.V. McCollum.
